Using terminal mode with 4.0 on the box, I can connect to the ISP, it says
CONNECT 115200, then nothing. When 3.4 was on the box, and with the
machine I'm on now (still 3.4 until I get this PPP thing figured out), I
get the old-fashioned login: prompt. So it seems there's something about
4.0-RELEASE and ppp on this machine that's causing PPP to freeze up early
